PURPOSE:To obtain the energy guide for intermediate infrared rays, whose output power is not fluctuated by a bending state by forming spirally a copper wire, forming a gold plating layer on its surface, and thereafter, eliminating copper of the inside by thick nitric acid, and forming a hollow waveguide made of gold. CONSTITUTION:In order to make a spiral thin gold tube, a copper wire is formed spirally and the surface of copper is plated by gold, and also, by immersing it in thick nitric acid, copper of the inside is smelted and eliminated. As a result, gold of a shell is left, and a hollow waveguide of gold can be formed. Accordingly, since the hollow waveguide is spiral shape from the beginning, there is no optical component which passes through by only traveling straight, even the component which goes into any direction advances in the waveguide, while being brought to multipath reflection. In such a way, even if the waveguide is bent, a loss does not increase newly, that is, the energy guide which is excellent in a characteristic against bending, and whose emitted optical power is stable can be obtained. |
